1. QUERCETIN SUPPLEMENTATION PREVENTS CHANGES IN THE SEROTONIN AND CASPASE-3 IMMUNOREACTIVE CELLS OF THE JEJUNUM OF DIABETIC RATS
RESUMO CONTEXTO: A serotonina (5-HT) está presente nas células epiteliais enterocromafins (CE), nos mastócitos da lâmina própria e nos neurônios entéricos. A 5-HT está envolvida na regulação da motilidade, secreção, nocepção intestinal, sistema imunológico e inflamação. Objetivo: Avaliar os efeitos do diabetes e da suplementação de que

2. The expression of endothelial and inducible nitric oxide synthase and apoptosis in intestinal ischemia and reperfusion injury under the action of ischemic preconditioning and pentoxifylline
Abstract Purpose: To investigate the expression of nitric oxide synthase (NOS) and apoptosis associated with ischemic preconditioning (IPC) and pentoxifylline (PTX) in intestinal ischemia (I) and reperfusion (R) injury. Methods: Thirty male rats were assigned to 5 groups: (CG), no clamping of the superior mesenteric artery (90 minutes); (IR-SS) saline +

3. Ghrelin plasma levels, gastric ghrelin cell density and bone mineral density in women with rheumatoid arthritis
Generalized bone loss can be considered an extra-articular manifestation of rheumatoid arthritis (RA) that may lead to the occurrence of fractures, resulting in decreased quality of life and increased healthcare costs. The peptide ghrelin has demonstrated to positively affect osteoblasts in vitro and has anti-inflammatory actions, but the studies that correl

4. Erythropoietin reduces storage lesions and decreases apoptosis indices in blood bank red blood cells
ABSTRACT Background: Recent evidence shows a selective destruction of the youngest circulating red blood cells (neocytolysis) trigged by a drop in erythropoietin levels. Objective: The aim of this study was to evaluate the effect of recombinant human erythropoietin beta on the red blood cell storage lesion and apoptosis indices under blood bank conditions.

5. Myenteric plexus is differentially affected by infection with distinct Trypanosoma cruzi strains in Beagle dogs
Chagasic megaoesophagus and megacolon are characterised by motor abnormalities related to enteric nervous system lesions and their development seems to be related to geographic distribution of distinct Trypanosoma cruzi subpopulations. Beagle dogs were infected with Y or Berenice-78 (Be-78) T. cruzi strains and necropsied during the acute or chronic phase of

6. Evaluation of immunohistochemical expression of ghrelin-producing rectal cells in Wistar rats underwent to the cafeteria diet
PURPOSE:To investigate the impact of cafeteria diet on ghrelin expression in rectal tissue and identify the morphologic cell type. METHODS:Twenty-four male Wistar rats were divided into four subgroups of six animals each: RC1 (rat chow 1) and CAF1 (cafeteria diet 1) for a period of 30 days; RC2 (rat chow 2) and CAF2 (cafeteria diet 2) for a period of 60 days

7. Importância do tecido adiposo marrom na ativação da termogênese induzida pela injeção central do C75, um inibidor da ácido graxo sintase / Importance of brown adipose tissue in the activation of thermogenesis induced by central injection of C75, a fatty acid synthase inhibitor
C75, a synthetic inhibitor of fatty acid synthase, causes anorexia and weight loss in rodents, but the underlying mechanisms are not totally known. Thus, the hypothesis tested in this work was that brown adipose tissue (BAT), an organ with important role for control of thermogenesis, could be involved in the anti-obesity effects of fatty acid synthase inhibi

8. The influence of selected pathological states on the somatostatin-like immunoreactive (SOM-LI) endocrine cells in the mucosal layer of the porcine descending colon
This study reports on changes in the number of somatostatin-like immunoreactive (SOM-LI) endocrine cells in the porcine descending colon, caused by chemically driven inflammation, axotomy and proliferative enteropathy (PE). The distribution pattern of SOM-LI endocrine cells has been studied using the routine single-labelling immunofluorescence technique. Sem

9. Hypoxic-ischemic injury decreases anxiety-like behavior in rats when associated with loss of tyrosine-hydroxylase immunoreactive neurons of the substantia nigra
Neonatal Sprague-Dawley rats were randomly divided into normal control, mild hypoxia-ischemia (HI), and severe HI groups (N = 10 in each group at each time) on postnatal day 7 (P7) to study the effect of mild and severe HI on anxiety-like behavior and the expression of tyrosine hydroxylase (TH) in the substantia nigra (SN). The mild and severe HI groups were

10. Morfologia, imuno-histoquímica e aspectos ultraestruturais das células imunorreativas à insulina no intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) adulto / Morphology, immunohistochemistry and ultrastructural aspects of insuline immunoreactive cells in small intestine of the opossum Didelphis aurita (WIED-NEUWIED, 1826) adult
Esta pesquisa teve como objetivo geral descrever os aspectos morfológicos, histoquímicos e imuno-histoquímicos do intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) adulto, bem como as características ultraestruturais dos grânulos secretores de células imunorreativas à insulina nesse animal. A biogênese dos grânulos insulínicos e a s

11. Induction of Zenk protein expression within the nucleus taeniae of the amygdala of pigeons following tone and shock stimulation
In this study, we evaluated the expression of the Zenk protein within the nucleus taeniae of the pigeon’s amygdala (TnA) after training in a classical aversive conditioning, in order to improve our understanding of its functional role in birds. Thirty-two 18-month-old adult male pigeons (Columba livia), weighing on average 350 g, were trained under differe

12. Aversive stimulation during the stress-hyporesponsive period does not affect the number of corticotroph cells in neonatal male rats
Immunohistochemistry was used to evaluate the effects of neonatal handling and aversive stimulation during the first 10 days of life on the number of corticotrophs in the anterior lobe of the pituitary of 11-dayold male Wistar rats. Since adult rats handled during infancy respond with reduced corticosterone secretion in response to stressors and with less be
